Screen blanks even though USB keyboard is used - Portable

This is a discussion on Screen blanks even though USB keyboard is used - Portable ; The screen blanks after 300 seconds even while I am typing on the
second keyboard (connected to the laptop through USB).
The screen unblanks when any key on the laptop is hit.
Any idea why?
I'm running Red Hat 9 ...

Any setting in the BIOS setup to shut off the backlight? Setterm
only blanks the screen unless APM enabled for backlight off too.
Been awhile since I did this by the way.

Let me formulate my question in a different way.

On a dual-boot RH9/Windows XP machine, why does the external (USB)
mouse or keyboard wake the machine up from its screen saver under
Windows, but does not under linux? (the BIOS settings remain untouched
between boots).

What machine are we talking about? My thinkpad 600E, (though not dual
boot) wakes up fine with an external USB keyboard and/or mouse as does my
non branded desktop.

Not RH, but I don't see that making much difference.

In that case your second post nbr.1 seems probable. Sorry can't
suggest anything for that.. But does nbr2 work i.e. no blanking
still ignored?
